Working Principles

The SN74LVTH162245DGGR is a level shifter and bus transceiver IC that facilitates data transfer between two different voltage domains. It operates by receiving data from one port, translating the voltage levels, and transmitting the data to the other port. The direction of data flow is determined by the control inputs provided externally. The IC also features 3-state outputs, which allow multiple devices to share the same bus without interference.
